|Chapter 5: | |Structure and Preparation of Alkenes. | |Elimination Reactions | Summary Alkenes contain the C=C functional group which can be prepared by 1‚2-elimination reactions such as: • dehydration of alcohols (- H2O) or • dehydrohalogenation of alkyl halides (- HX). Zaitsev’s rule indicates that the preferred product is the more highly substituted

Other nitrogen containing compounds Catecholamine: Dopamine‚ norepinephrine (noradrenaline) and epinephrine (adrenaline) are biologically active amines and are collectively called as Catecholamine. * Dopamine and norepinephrine functions as neurotransmitters. Outside the nervous system‚ norepinephrine and its methylated derivative‚ epinephrine regulates carbohydrate and lipid metabolism. They are released from storage vehicles in the adrenal medulla in response to stress (fright‚ exercise‚ cold

EXPERIMENT 5- A FISCHER ESTERIFICATION SYNTHESIS OF PEAR OIL One of the major uses of Esterification (C(=O)-C-R) is forming compounds with different odors which can be used to make different synthetic and natural flavorings. Using the chemical and physical properties of organic compounds‚ an ester was catalyzed from the reaction of a carboxylic acid with an alcohol‚ producing an odor similar to that of pear oil. The mechanism of this Fischer- Esterification process is outlined as follows:

Online Mock Test and Exam Management System Abstract Online Examination System is a software solution‚ which allows a particular company or institute to arrange‚ conduct and manage examinations via an online environment. This can be done through the Internet‚ Intranet and/or Local Area Network environments. Some of the problems faced by manual examination systems are delays in result processing‚ filing poses a problem‚ filtering of records is not easy‚ The chance of loss of records is high

ALCOHOLS Alcohols are compounds in which one or more hydrogen atoms in an alkane have been replaced by an -OH group. For the purposes of UK A level‚ we will only look at compounds containing one -OH group. For example: Primary alcohols In a primary (1°) alcohol‚ the carbon which carries the -OH group is only attached to one alkyl group Some examples of primary alcohols include: Secondary alcohols In a secondary (2°) alcohol‚ the carbon with the -OH group attached is joined directly to

Empirical Formula of a Compound * Purpose: To determine the empirical formula of Magnesium Chloride. * Data 1. Mass of evaporating dish = 45.08g 2. Mass of evaporating dish and Magnesium = 45.17g 3. Mass of Magnesium: { 2 } – { 1 } = 0.09 4. Mass of evaporating dish and Magnesium Chloride First weighing = 45.48g (After heating and cooling) second weighing = 45.49g 5. Mass of Magnesium Chloride: { 4} – { 1 } = 0.41g

A carbohydrate is an organic compound that consists only of carbon‚ hydrogen‚ and oxygen‚ usually with a hydrogen:oxygen atom ratio of 2:1 (as in water); in other words‚ with the empirical formula Cm(H2O)n. The carbohydrates (saccharides) are divided into four chemical groupings: monosaccharides‚ disaccharides‚ oligosaccharides‚ and polysaccharides. In general‚ the monosaccharides and disaccharides‚ which are smaller (lower molecular weight) carbohydrates‚ are commonly referred to as sugars.
